DAVID H. DONALDSON, OF BUFFALO, NEWV YORK.

HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 297,117, dated April 22, 1884. Application filed October 8, 1883. (No model.)

T all whom it may concern.-

Be it known that I, DAVID H. DONALDSON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Hasps and Looks for Same, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention consists in the construction of the upper part of the hasp and a swinging piece,wl1iol1 attaches to a door, sill, a box-lid, or other place, by which the upper part completely covers this swinging or hinged part, to which the screw or bolt is attached that fastens the hasp to a door or other place.

It also embraces, in combination with the above-described construction, the construction of the hasp with an oblong opening and an oblong bulb-lock having a screw-point attached to it adapted to be inserted in the work by turning the bulb.

In the drawings, Figure 1 is a side elevation of my device fastened to two pieces of wood; Fig. 2, a perspective of the hasp; Fig. 3, perspective of the bulb-lock detached.

A represents a hasp with a recess, a, in its upper inside part, which receives therein a swinging-piece, b, which holds the bolt or screw d, and when in place is flush with inner surface of the hasp, so that it can be used on two straight surfaces, as in Fig. 1.

The piece I) swings by a pin, 0, running through the upper part of the hasp A, as shown, and the screw (2 fastens the hasp to the cover, lid, door, or other place.

B is an oblong or oval opening in the lower part of the hasp, to admit a combined staplebulb and lock, 0, which is also of oblong or oval conformation, coming to a point in front and flat on the back, and which, by means of a screw or bolt, f, attached or forming a part thereof, is fastened into a door, D, or other place. The opening Bof the hasp goes over the bulb, as in Fig. 1, rests against the wood D, and incloses the sides of the bulb just enough to prevent the bulb being turned or twisted therein. In this bulb is alockmeoh anism of any kind, that by a key, 9, admitted in the end h.will throw out one or more bolts,

z, from its sides and against the face of the hasp, as shown. This effectually prevents the hasp being lifted off until the bulb is unlocked.

The great advantage of this device is that one end secures the other, the main object being to cover the upper or hinged end of the hasp to prevent its being pried off if nails are used, or unscrewed if screws are used, as is usual.

I do not claim, broadly, a bulb-lock, nor

any particular lock mechanism.

I claim- I 1. The combination of thehasp A, having the recess a in its upper inner surface,and the hinged or swinging piece b, setting therein and holding a screw or bolt, 01, to fasten it to a door or other place, substantially as specified.

. 2. A hasp and lock consisting of the hasp A, having the recess a in its upper inner surface, and the hinged or swinging piece b, set

ting therein and holding a screw or bolt, (2, to fasten it to a door or other part, an oblong opening, 13, in the hasp A, and an oblong bulb-lock, O,having the screw-pointf, adapted to be inserted directly in the wood by turn- 7 5
